Japanese blog Mac Otakara posted a new report tonight which indicates that Apple will maintain the Lightning connector on the 2019 iPhones but may finally be including an 18W Fast Charger and USB-C to Lightning cable.
In addition, the next iPhone seems to continue to adopt the Lightning connector, but the charging cable has been changed to the USB-C to Lightning cable, and it seems that the attached power adapter may also be changed to the Apple 18W USB-C power adapter is.

The inclusion would represent an upgrade to the currently shipping 5W USB adapter. The 18W adapter allows fast charging with iPhone X charging from 1 percent to 79 percent in one hour.
This rumor actually contradicts a previous report by the same site which expected Apple to retain the 5W adapter. Mac Otakara also reiterates Ming-Chi Kuo's claim that this year's iPhones will have the ability to wirelessly charge other devices.
